Cov yam ntxwv ua tau zoo thiab cov txheej txheem ntws ntawm cemented carbide strips

Cov yam ntxwv ntawm kev ua haujlwm:
Cemented carbide strips muaj zoo heev warp hardness, siab hardness, zoo hnav tsis kam, siab elastic modulus, siab compressive zog, zoo tshuaj stability (acid, alkali, kub oxidation), tsis tshua muaj tej yam toughness, expansion coefficient tsawg, thermal conductivity, hluav taws xob conductivity. zoo ib yam li hlau thiab nws cov alloys.
Txheej txheem khiav:
Ua hmoov nplej → formulation raws li daim ntawv thov → ntub sib tsoo → sib tov → crushing → ziab → sieving → ntxiv forming tus neeg sawv cev → rov ziab → sieving kom tau ib tug sib tov → granulation → nias → sib sau → tsis tshua muaj siab sintering → sib sau (dawb) → Kev kuaj xyuas qhov tsis zoo → ntim → cia.
